Shulker mob will glitch you a into a block when floating

Ok so I was playing one of my survival world with one of my friends as I do and we find our second end city and we were happy so both of us got elytras and the shulkers were annoying as they always are and it glitched me into one of the roofs and I thought it was cool cus I didn't suffocate and I was just randomly in a bock (by the way we have been playing this world for 2 months every day or every other day) so we got the stuff from the end city and left later on I went through a block he placed and we were so confused so we left and rejoined and later we went to the end city and back and the same glitch happned so we guess it was the shulkers because I got I The block from them the first time we thought it was cool till it killed me in our no keep inventory world in the nether and all my stuff randomly disappeared when I went back and I lost everything I had I know you can't get my stuff back I would love it if you could but anyways the least that you guys at Microsoft support please fix this because I don't want anyone else to get annoyed at this glitch
